T0 all wiz0m z't may concem:

Be it known that I, LEON R. CLAUSEN, a

' citizen of the United States, und a resident of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Side-Delivery Rotary Rakes, of which the following is a specification, reference being had to the accon1panying drawings.

This invention relates to side-delivery rotary 1akes of the type wherein the rotary reel is arranged at an angle to the line of draft of the wheeled supporting frzune, to the axle of which the frame of the rotary reel is pivotally secuted, the several series of rake-teeth With Which the reel is equipped being maintained at the same angle so as to be presented properly to the hay that is to be raked. Such teeth ZLI6 hold in the desired uniform working position by the employment of suitable mechanism carried by the forward or inner reel-head and comprising, generally, a set of gears in connection with each tooth bar and a Single other gear placed centrally with respect to the several sets and in mesh with the inner one of each of seid sets of gears.

It has been common to provide at the rear of the reel-frame and near its outer end one or more caster-wheels between which and the reel-frame a.vertical relative adjustment could be effected,-th'e said frame during such adjustment rocking about the axle of the machine as an axis. In making such an adjustment, it is evident that the outer or rear end of the reel-frame und also the reel that is supported in such frame will move through a greater arc than the inner or front end of such frame and rcel, and it is sometimes desirable that such inner or forward end of the real be given a'n adjustment additional to that which is secured by the character of adjustment above referred to, but it is also desimble that this additional adjustment be confined to the reel itself as distinguished from the adjustment of the reel and its frame together. O11 account of simplicity of construction it is desirable to drive the reel-shaft directly from the mein axle by means of two intermeshing bevel gears securedrespectively to the shaft and axle. es fully shown and described in the Letters Patent to Joseph Dain, N0. 886,681, dated May 5, 1908, but it is also deSirable that prov1si0n"be made for simultaneolmly shifting the angle of the various tooth bars by slightly 1otating the gearing carried by the inner reel-head, as above referred to which latter operation would prevent the independent vertical adjustment of the inner end of the 1eel if the adjusting lever were rig1dly connected with the freme. I lmve, therefore, made use, in connection with the present invention, of my invention set forth in Patent N0. 1283674= granted November 5, 1918, upon 1ny application, which, while primarily designed for allowing fo1 a, lateral adjustmentof the reel, Will also allow of a vertical adjustment of the reel with respect to its frame. It is the object of my present invention to furnish a construction by which the inner end of the reel may be vertically adjusted and the bevelgear 011 the inner end of the reel-shaft maintained at all times in proper connection with the main driving gear on the axle, and also ellow the shifting mechanism connected with the gears on the inner reel-head t-o be connected with the reel-frame. I accorn plish this object by the construction and a1- rangement of parts shown in the drawing and hereinafter fully described. That which I believe to be new and desire to cover b *y this application is set forth in the claims.

In the drawings Figure 1 is a plan view of a side-delivery rotary.rake embodying my improvements;

Fig. 2 is a detail, being a view in elevation of a portion cf the inner cnd of the reel-frame, the axle of the wheeled support being shown in section, es is also the reelshaft, upon which shaft is shown the bevel gear that is driven from the gear on the rotating axle.

F ig. 3 is a detail, being a view from the opposite side of the portion of the frame that is shown in Fig. 2 and showing the means employed for eflecting a raising and lowering of the reel-shaft with respect to the reel-supporting f'1ame;

Fig. 4 is a detail, being a side view of a portion of the driven bevel gear secured to the reel-shaft;

Fig. 5 is a detail, being a central section through the inner head of the rotary reel showing a portion of the gearing mounted on .said head, the view also showing the lever and pivoted sector construction through Which the gears on the reel-head may be adjusted t0 change the angle cf the rake-teeth; and

F ig. 6 is a partial :E-ace vieW 01 fl1e gear 011 the axle that meshes With the p1 n1on 011,

11 so as to rock freely there0n When the frame is adjusted relative to its usual rear ground-engaging support 01 supports. In

Ehe construction shown the connecting 01 the frame 12 is through the medium 01 a bent supplemental frame member 13&that is rigid1y connected with and forms an extension 01 the ma in frame 12. 1 have sh0wn the machine provided with two groundengaging suppo'rts in ehe forma of. casterwheels, ezich 0f which is indicated by 14. Each caster-wheel is mounted in a yoke 15 from Whichrises a Standard 10that has a sliding connection in bearings carried by an arm 17 thatis secured to and projects rear- Ward1y from the reafbar 01 the frame 12. F rom eachof the standards 16 extends a connection comprising a chain mcmber 18 and a linkmemberl9, the forw ard ends 0f 'the two link members being connected t0 a common adjusting' lever that is mounted on the usual long truss bar 20 that extends frorn the whee1ed support back a nd over the reelframe. The chain members of thesc said connections pass under suitable pulleys journaled 011 the reel-frame so that when a p1il1 is exerted 0n ehe connections 1819 by means 013 their common 1ever 011 the truss bar the ree1 frame Will be adjusted vertically relative to the supporting 1 caster- Whee1s. The details 0f this fr'ame-adjusting mechanism are fu1ly shown and described in Letters Patent N0. 1,313,880, dated August 27, 1919, granted upon my application.

The reel that is rotatably mounted in the frame 12 comprises tw0 heads connected together by a plurality of bars, to which bars the rake-teeth -are connected in"thc usua1 manner. The inner or forward 0ne of these reel-heads is indicated by 21 and the outer or rear ree1-head is indicated by 22. Two 0f thetocth bars a1e shown in Fig. 1 and it is intended thabthree of such bars Will be empl0yed, as fully set forth and 1 described in said Dain patent and my said Patent N0. 1,283,674. The tooth bars he1e shown are indicated by the numeral 23. 24 indicates curved guards that are secured at regular intervals t0 ehe fr0nt ancl rear members 01 the reel-frame und act to free the rake teeth fr0m any hay that might tend t0 be carried around with such teeth.

The inner 0r forward reel-head 21 has r0tat-ably secured 0n its outer face a plurality cf sets cf gears, the numbei 0f sets corresponding in number 130 the number 01 the tooth bars 23, and in the outer ge ar of cach set Ehe forward end 01 one 0'f the tooth bars Will be secured asusual. In Fi'g. 5 is shown in section one 015 the three sets 01 gea1s mentioned and also the central gcar that is in mesh with the inner one 01 euch cf the several sets. The outer gezir here show n is indicated by 25 and the gear that is in mesh therewith is indicated by 26, such gear 26 being journaled upon a pin 27 made fast to the reelhead. The sm-aller central gear referred t0 is indicated by 28, und whi1c such gear28 is normally held fixed against r0tation it may be rocked 011 the cylindrical hub over which it is shown as fitting, such rocking being 130 efiect a change in .the positi0n 01 the several-tooth bars. so as to incline t0 the desired extent Ehe rake-teeth carried by such bars In "sald Fig. 5 there is shown a lever and a m0vable sector construction, by the use cf which this rocking of the central gear may be accomplished. The lever is ind1cated by 29 and is rigidly fixed at its inner end t0 a small central gear 28, its outer end porti0n extending alongside 'of the sect0r referred to so as 130 be locked thereto 'at any desired point by means 01 an ordixiary spring latch (not shown) carried by%he The nocched sect0r referred t0 is indicated by 80. Ic is pivotally attached t0 the front bar cf theneel-frame 12 at 31 and its under edge rests 100se1y upon a pin 01 bracketprojecting from che lever. Th'is lever und pivoted sect0r c0nstruction is setf0rth very fully in my said Lettiers.Patent N0. 1283,674. 1 32 indicates the usual ccnt1a1 shaft of the r'cel up0n which the reelheads 21 and 22 are suitably secured so as t0 turn therewit-h. The shaft is preferably angular in cross-secticn as shown; v The 0uter end bearing f01 this shait 32 i.s t0 be luge enough so -as t0' a110w the' shaft t0 have a limited rising and 1"alh' 11g movement when p0wer is applied -t0 the inner cnd thereof, as hereinafter de sc1ibed, in order that the forward or inner c'nd 0f the 1ee1 may be adjusted indepencL ently cf any adjstment fgiven t0 its supporting fraine,that is independently cf 'che adjustment efiected through a movement 0f the connections 18-19 that lead to the ground-engaging upports. 111 0rder to effect this indepcndent vertical adjustment 0f the fcrward 01 inner cnd 01 the reel-shaft such inner encl is supported in an adjustable member capable 0f being helcl in clifierent adjusted positions in a vertically slottecl bracket 33 clepencling f1om the fraxnework, which bracket, in ehe construction shown, is formecl integral with e slecve me1nbcr 3% through which passes the axle 11. 35 indicates a vertical slot in the brachet, in the fo:rwarcl eclge of which is f0rn1ecl, as shown, a series of teeth 36 that censtitute a nach with Which mesh thc teeth 0f a pinion 37 that is rotatably mountecl 011 the cylinclrical surface of a sleeve 38 fittecl over the reelshaft. Inasmuch as the rack 30 is comparatively short the entire periphery cf the pini0n is not providecl with teeth, ancl hence such pinion n1aV properly be tenned a mutilatecl piniea1. The untoothecl ortion eE :he periphery of this pinion bears against thc opposite eclge of the slot ancl thus insu1es the teeth of the pinion being helrl in engagement with the 1ack. The raising anal luwering of the inner 01 forwarcl eu l 015 he reel-shaft is accomplished by means 0 5 an acljusting 1ever 39, which, as best shown in Fig. 3, is boltecl t0 an arm 40 that is formed integral Witl1 an annular flange 0111 the ou'tcr en(l of the mutilated pinion, such flange bearing against the inner face 0fthe bracket 33 at euch sicle cf the longitudinal slot As this lever 39 is turnecl it is evident that through the meshing of the teeth o-E the mutilatecl pinion 37 with the 1ack 36 the pinion must be vertically 1novecl accorcling t0 the clirection in which the levcr is moveal, ancl, of course, will carry with it the reelshaft that projects thro:ugh ancl has a bearing in the short sleeve on which the pinion is rotatably mounted. When the clesi1ed adjustment has been attainecl the adjusting .lever 39 can be locked t0 a notchecl seg1nent 41, the engagement cf the lever with the segment being by means of an orclinary spring latch that Will be carriecl by the lever.

The means lt'01 rotating the 1eel comprises, in the constructicn shown, a large bevel gear 42 carlied by the axle, 11 and aclapted to l e c0nnected with said axle so as to rotate therewith ab Will by an v .suicable clutch mechanisma clutch for this purpose beinq inclicated generally in Fig. l b the n1uneral -1l3 tl1e pat"c 019 he clucch movable along ne axle having attached to i'a handle +=el. Conscituting a part cf the reel-clriving means is a hevel pinion 45 fast 011 he projeczing in ner forward encl 0f ehe reel-shaf and in n1esh with he bevel gear 4-2.

The bevel pinicn 'l5 clifi'e1s in construction fionn the ordinary bevel pinien, in that each cf its teeth has its sicle faces bevelecl from the center o1" the teeth towarcl the encls in stead 0'f having each face beveled in straight line frorn encl t0 end 01" the toeh.
